IPC: C08F232/08
Filed: 1974-01-23
Abstract: 1447903 Resins for printing ink NIPPON OIL CO Ltd 23 Jan 1974 [23 Jan 1973] 03125/74 Heading C3P Resins suitable for use in printing inks and having softening points of at least 100‹ C. are obtained by reacting together (A) a resin obtained by thermal polymerization at 150-350‹ C. in the presence or absence of an inert hydrocarbon solvent of a mixture of (i) at least one of cyclopentadiene, dicyclopentadiene or C 1-3  alkyl-substituted derivatives thereof and (ii) an unsaturated alcohol or an organic acid ester thereof, and (B) a C 8  or higher saturated or unsaturated monocarboxylic acid. When resin (A) contains monomer units (ii) which are esters, the reaction with (B) may occur directly by transesterification or an intermediate hydrolysis step may be effected to produce hydroxyl groups. The products may also include reacted rosin or resol-type phenolic resin. In examples, (1) dicyclopentadiene/allyl alcohol copolymer is reacted with linseed oil fatty acid; (2) dicyclopentadiene/crotyl alcohol copolymer is reacted with tall oil fatty acid; (3) a copolymer of a mixed C 5  dimer with cinnamyl alcohol is reacted simultaneously with castor oil fatty acid and maleinized rosin; and (4) dicyclopentadiene/ vinyl acetate copolymer is hydrolysed, then reacted with eleostearic acid, and then further reacted with a resol-type phenolic resin.

Title: Impact absorber for washing machine - using component materials of sufficient coefficient of friction and noiseless operation
Inventor: LAFILLE ALAIN
IPC: F16F7/08
Filed: 1974-06-18
Abstract: Impact absorber for washing machine is mounted between the tub and frame of the machine and comprises at least one spring element of which at least one end carries a shoe of which the surface moves frictionally over the surface of a rigid flat part.

Title: Child's modelling game - uses flexible wire threaded through tubes embedded in moulded parts with relative movement
IPC: A63H33/32
Filed: 1975-01-28
Abstract: The mould is in two halves which together determine the shape of the article to be made. Once these have been filled with material in a plastic state, and before they are fitted together, a component is inserted between them comprising a wire of malleable material such as lead, over which a number of tubes (5) of plastic, such as polyethylene, are threaded, so as to form an articulated assembly. When the halves (1, 2) are fitted together, the tubes are encased in the material, while the wire allows a certain amount of articulation between the parts formed (3). Thus the child playing with the game can move the extremities in relation to the main body of the shape without detaching them.

Title: Pyrotechnic charge remote firing process - emits coded signal by carrier wave resulting from combination of basic signals
IPC: F42C13/04
Filed: 1975-04-08
Abstract: The process fires a pyrotechnic charge by remote control, emitting by a high-frequency carrier wave a coded signal resulting from the combination of two or more basic signals from among a set of signals of different frequencies. At the charge, the signal is received and demodulated, being then passed through a series of filters corresponding to each of the basic units, and of the same number. A command signal is then produced to fire the charge when the outputs of the filters correspond to a predetermined state signal. The emitter (10) is powered by a battery (12). The insertion of the modulation 14) is relayed by a rotating commutator (18) passing through (n+1) positions.

Title: Programmable signal generator with scanning of charted function - moves linear potentiometer slide to generate output electrical signal
Inventor: CZERNY HERIBERT
IPC: G05B19/12
Filed: 1975-09-22
Abstract: A programmable signal generator allows a chart recording of a digital or analogue function to be scanned photoelectrically to generate an electrical signal reproduction of the function. The chart recording is produced as an endless band with the function marked as a line diagram of high contrast. A photoelectric transmitter and receiver is coupled to a cylindrical sliding core of a linear motor. The sensor is supported on a guide rod and an output signal is generated from a linear potentiometer. The sensor output intensity is used to control a pulse width modulation circuit controlling the linear motor to stack the recorded characteristic. A stepping or synchronous motor is used to drive the chart through a gearbox. A control track s scanned by a second sensor to generate control signals for the drive. The chart is contained in a plug-in cassette.

Title: Laser cutting process for food prods - using protective gas to remove vaporised matter
IPC: B26F3/16
Filed: 1976-03-29
Abstract: Cutting process and plant is intended for food prodts., notably those produced by the bakery trade, the pastry makers and biscuit factories. When using ordinary knives, the zone of sepn. tends to be compressed and deformed. In the new method the prod. is cut by a laser beam, using a protective gas at the point of cut. The cooked biscuit dough leaves the continuous cooking oven in the form of a rectangular strip on rollers. The laser cutting head is mounted on the transverse girder of the carriage; this moves, on the rails at right angles to, and in synchronism with, the moving strip. The laser beam is generated and is reflected by mirrors through the cutting head. At the same time an inert gas. pref. nitrogen, is directed into the cutting zone so that the biscuit vaporised by the laser beam is blown away from the zone of the cut. A cut is obtd. without actual contact with no compression in the cutting zone. The cut is perfectly clean and very interesting from the hygienic point of view.
